1. A current-sensing resistor for measuring an electric current, having
a) a first connection part made of a conductor material for introducing the electric current to be measured into the current-sensing resistor,
b) a second connection part made of a conductor material for discharging the electric current to be measured from the current-sensing resistor,
c) a resistor element made of a resistor material, the resistor element being arranged in the direction of current flow between the first connection part and the second connection part so that the current to be measured flows through the resistor element,
d) at least one pair of voltage-sensing contacts for measuring a voltage drop across the resistor element, the voltage-sensing contacts each engaging one of the connection parts, and
e) at least one incision in at least one of the connection parts, the incision surrounding one of the voltage-sensing contacts and preventing a current flow across the incision,
f) wherein a plurality of pairs of voltage-sensing contacts are arranged one behind the other in the direction of current flow.
